Application filed April 3,1905. Serial No. 253,6l6.

To all whom it may concern:

Be it known that I, STEPHEN HARRY Pococn, a citizen of Canada, and a resident of St. Catharines, in the county of Lincoln and Province of Ontario, Canada, have invented new and useful'lmprovehnents in Cash- Registers, of which the following is a specification.

My invention relates to improvements in cash registers in which horizontal push keys are arranged to rotate certain numeral disks by means of vertical graduated lifting racks, and said keys adapted to lift vertical indicators by means of graduated connecting rods pivotally connected to the frame and to the indicators.

The invention also contemplates providing means for retaining the keys when pushed to the rear until released by independent initial keys; also certain rollers one above the other for engagement of the keys to prevent the operation of more than one key in one bankof keys at a time.

Figure 1, is a front elevation of the machine the front part of the framework being removed. Fig. 2, is a front elevation of the rear part of the machine, the keys thereof being shown in section. Fig. 3, is an enlarged front elevation, or face of one of the numeral disks.

Fig. 4, is a side elevation of the machine as viewed.

from the righthand side thereof, or unit side of the machine showing the mechanism of the first bank of keys, the other bank of keys being similar. Fig. 5, is a sectional elevation of the machine looking from the right showing the mechanism between the tens of units banks. of keys and the lower initial key marked B, in Fig. 1 of the drawing, th lower initial key marked 0, in Fig. l of thedrawing being similar. Fig. 6, is a detail side elevation of the lower part of the transferring device as partially shown in Fig. 5 of the drawing. Fig. 7, is a side elevation ofthe rear end part of the lower initial keys, one of which is shown .as the lower key in Fig. 5 of the drawing. Fig. 8, is

a'plan of Fig. 7 of the drawing. Fig. is a front e1evation of the machine, the front part removed. Fig.

10, is a plan of the rear part of the machine showing the indicator rods in section. Fig. 11, is an enlarged sectional detail of a common spring plunger of the machine all of which are of similar construction. 12,. is an enlarged detail elevation of a few of the rollers.

Similar letters refer to similar parts throughout the several views.

In the drawing the stationary is indicated by A, the upper horizontal stationary shaft by D, and the shaft bearings by E. All the horizontal push'keys, are, for convenience, indicated by K, except the two lower initial keys B and O. The initial keys B and G are for use by different clerks. The rear end part of the keys K have upper ratchet teeth 12 frame of the machine:

and extend through the rear side of the frame A. The levers 13 are pivotally connected to the rear of the frame and fit into the ratchet teeth 12 and allow any one of the keys to be pushed, and to prevent any one of the keys K from being withdrawn. The levers 13 have frontwardly projecting pins 14 which fit into the recesses 15 of the false back 16 shown in Fig. 2, of the drawing.

17 are guidesfor the false back and allow the same to be slightly raised by means of the incline brackets 18 on the side of the rear part of the initial keys 1%. and C. The inclined bracket 18, passes through the ripening 19, in the false back 16 and consequently raises the same, 'when a key B or G is pushed.

-. 20 is a spiral tension pull spring connected to the false back 16 and to the frame A. The front part of the keys K are provided with inclined brackets 21 on the side of said keys, the front end of the brackets 21 abut the inner side of the frame A. The top of the brackets have-lips 22 which fit in recesses 23, in the sides of the graduated lifting rack 24 when said rack is raised by means of the bracket 21 engaging the roller 23 extending from the sides of the lifting rack 24. The lower end of the rack 24 has a vertical slot 2-5 which guides the rack by means of the guide pin 26 of the frame A. The upper end of the rack 24 has ratchet teeth 27 which are adapted to rotate the ratchet wheel 28, together with the numeral disk 29 next to said rack 24, and on the shaft D.

30 are spring controlled plungers in casing 31 on the frame A in rear of the wheels 28. The plungers engage the teeth of the wheels 28 and prevent the same from rotating the opposite way to thatindicated by arrow above the disk 29. The indicators 32 above the top of the machine, have lower extending rods, or stems, in guides 33, and to which the slotted ends of the connecting rods 34 are connected, the opposite and higherend of the rods 34, being pivotally connected to the frame A, at 35. I

The connecting rods 34 are lifted by graduated lifting brackets 36 on the keys K. The lower lifting bracket 36 lifts the lower connecting rod 3 1 by means of a pin 37 onsa-id bracket. When a key K, is pushed, a rod 34 is lifted, consequently an indicator to which the slotted end of a rod 34 is loosely connected is raised' S, are spiral pull springs connected to the push keys, and the opposite end of said springs S, are connected to the frame A.

R, are a series of rollers adapted to roll loosely on the ed to vertically slide on said shaft. The rollers R. rest one upon the other, and the ends of each roller have slightly beveled, or chamfered edges, to afford an openingbetween each roller for the entrance of the incline teeth, or wedgelV, on the sides of the keys. It will be vertical stationary shaft T, and more particularly adaptnoticed that when any one key is pushed that the thin edge of the wedge V, enters the opening formed between the ends o'l the rollers It, and consequently all the rollcrs above the wedgeare raised sufliciently to allow the body part of the w dge to pass between the end part of the two rollers engaged. The lower of the two rollers mer ly revolves, but the upper roller of the two revolves and slides upward. There are as many shafts T, having rollers R, as there are banks, or partial banks, of keys K and placed between the odd numeral keys K, and the even numbered numeral keys K of any bank of keys, asshown in Figs. 4 and 5.

Theobject of the rollers R, is, to prevent any two keys in a bank from being operated at the same time, or, tvhen'ono key is pushed toward the rear, another key in the same bank ofkeys can not be operated, on account of the upper entrances for the upper wedges, to the one in use, being closed, and the lower entrances, to the one in use, being locked.

When a key K is operated or pushedto its limit in order to raise an indicator, said key must be released and allowed to resume its normal position by means of an initial key B or C as the case maybe, before another key K in the same set or bank can be operated.

The vertical shafts M, extend from the lower to the upper part of the frame A, and are capable of rotary motion, either way. The shafts ill, have a series of projecting pins N on diametrically opposite sides thereof, with which the inclined lips P, on the upper side of the keys, engage. When a key is pushed the lip P pushes the pin N, consequently the shaft M rotates until the lip P passes the pin N. The incline of the lip P, as shown, allows the key to return by gradually lifting the pin N, together with the shaft M, until the lip P has passed the pin, then the shaft M resumes its position by gravity. On the upper part of the shaft M, is a cam. wheel U secured thereto, said cam being adapted to reciprocate a lever 38, conveniently fulcrumed to a part of the frame at'39 shown in Fig. of the drawing.

It will be noticed that three shafts M, with their camwheels U and levers 38 are shown, and which are operated identically in the same manner. 40, are cases rigidly supported at 41 by the frame A. The rear end of the levers 38 are connected by a horizontal rod 42, and spring plungers 43 pass through the casings and one end of said plungers pivotally connect to the levers 38 at 44, and the opposite end of said plungers engage the indicator vertical rods 32. The springs in the easings 40 press the plungers 43 to contactrwith said vertical rods 32. 1 Ordinary spiral springs 40 in the casings 40 push the plungers 43 outward in a manner which is common.

When any one of the cams U are rotated by means of a key, as described, the cam presses its end of the lever 38 toward the right hand side of themachine' consequently the opposite end of the levers 38.t0gether with theplungers 43 are brought toward the left-hand of the machine consequently releasingithe indicators 32 from the influence and controlof the plungers 43. Each bank of indicators are controlled by the spring pressure plungers 43. It will be noticed that the unit indicators, and the tens of unit indicators have each two vertical rods.

In convenient proximity to the rear end part of the initial keys B and C is a ratchet wheel 46 adapted to rotate on its shaft 47 together blades 43, A spring blade 49 is on said end part of said keys and adapted to engage said blades in succession and rotate the wheel 46 one fourth revolution at a time. I

The tens of units and the hundred of units numeral disks 29 are provided with ratchet wheels 50, and the unit and tens of unit disks 29 have three pins 51 on the left hand side thereof. Vertical rods 52 (one each between numeral disks 32) are pivoted at 53 to a standard 54 of the frame A. Each rod 52 is provided with a gradual inclined lip 56, and an arni 58, which engages the ratchet wheel of said disks, and rotates the same. When the disks 29 rotate, as indicated by arrow, together with the rollers 51, and the ratchet wheel 50, a roller 51 engages the lip 56 of the pivotal rod 52 and causes the lower part of said rod to approach in proximity to an upper blade 48 of the ratchet wheel 46. When an initial key is pushed the spring blade 49 engages the l wer blade 48 of the ratchet wheel 50 and the upper blad." if; pushes the rod frontward to normal posi sition, as shown in full lines in Fig. (i, of the drawing. As the initial key returns, the spring blade 49 is adapted to fall to a lowerposition by contact with a blade 48. As shown in Fig. 6, other blades 48, operable by another spring pawl 49, are located on shaft 47 back of the other levers 52 for operation thereof by the other initial key or keys. The upper part of each rod 52 has a rearwardly extending arm 60 with beveled lip 61, and the standard 54 has a spring plunger 62 with beveled lower end to engage either side of the beveled lip 61 to retain the lip 61, in operative position to the pins 51 of a disk 29.

64 is a block on the underside of the rear part of the initial keys B and C (see Figs. 6 and '7) to hold the respective initial keys in normal position while a numeral key K, is in process of being pushed. These blocks 64 provvent release of the initial keys B and C by frame 16 except when the numeral keys are pushed all the way in, so that a partial operation of a numeral key will not release theinitial keys.
